Be it known that l, Gnonen J. CLAYTON, a citizen of the United States, residing at Lakewood, in the county of @cean and State ot' New Jersey, have invented certain new! and useful lu'iprovenients in Deinountable Rims, of which the following is a specification.

lThe invention has for its object to enable a tire to be readily placed in position or easily removed from a Vehicle wheel as occasion mayrequire, the invention relating to pneumatic tires .Zand rims cooperating therewith and which necessitate frequent removal of the tire for various causes.

lin accordance with the present invention, the riIn which is demountable comprises complemental parts which are separable, each part having a flange at outer edge between which the tire is secured when the parts are placed together.

The drawing illustrates a preferred ein bodiment of the invention. However, it is to be understood that in adapting thesame to meet different conditions, various changes in the form, proportion, and minor details of construction may be resorted to without departing from the nature 'oit' the invention as claimed hereinafter.. i

ln the accompanying drawing,

Figure l is an edge view of a deinountable rim embodying the invention, showing the conipleinental parts secured.

Fig. 2 is a view similar to Fig. l, shoiv ing the parts separated.

Fig. 3 is a transverse section on the line 3-3 of Fig, l, the'parts being illustrated on a large scale.

Fig. t is a side view of the rirn with a tire in position and showing au portion ot a wheel. i

Fig. 5 is a detail perspective view of one of the ties, whereby the parts of the riin are connected. ,"f

Corresponding and like parte are referred to in the following description and "indicat dl in the several views of reference characters.

The rim comprises similar parte l and 2, each being provided at its outer edge with a retaining {iange for coniining the tire and the two parts having their inner edges jointed to insure their alining. is illustrated most clearly in Fig. 3, the inner edges of the parts l and 2 are connected. by means of an overlappiiig joint, the parts being the drawing byli-he 4ing nieansfor the tire,

halved or rabbeted.

When the parts 1 and 2 are separated. a tire may be easily ren'ioved troni the rini or applied thereto. no matter what may be the toi-mation of the confining flanges and whether the tire has straight ,l

or beaded edges. .at suitable 'intervals in `thelcircunirerentuil length of theruu. openings 3 are formed in the side walls. A plate 4 is provided tor cach set oi opening and is disposed upon the outer tace ot the parts l and 2 between the side flanges thereof. as indicated inost clearly in Figs l and. The plate et is oblong and tapers troni the middle point toward opposite ends. The outer side of the plate if is straight between its longitudinal edges, whereas its innerside or that adjacent the rim is transversely conto conform to the transve1se curvature of the outer side of the rim. The plate t is of awidth corresponding to the distance between the flanges of the rim when the parts l and 2' are assembled. 5 extend from opposite edges of the plate le and are disposed midway the ends of the plate. The projections 5 are externally threaded and are adapted to pass through registering openings 3. Each projection oreceives a washer 6 and a nut 7. The inner .tace ot the washers 6 conform to the outer walls of the rirn, whereas the outer ends of the washers are placed to receive the binding action of the nuts 7 by means of which the parts l and :2 are drawn together and made secure.

The plate i with its lateral threaded eX- tensions' 5 constitute a tie by ineans of which the parts l .and 2 are held together in conjunction with the `washers 6 and nuts 7. lWhen the nuts and washers are removed the parts l and 2 comprising the rirn may be separated, thereby admitting of the tire being easily, quickly and conveniently placed in position or reino-ved trein the riin. When the tire is' in position the parts l and 2 'of thef rim are brought together and are made secure by placing the washers o and nuts 7 in position and tightening the nuts..

flh'e plates t constitute guides and suppm thereby greatly ta- Gilitating the assembling ot the parts when placing. a tire in position upon the rim and bringing the parts l and 2 together after the tire has been placed in position. |The construction is such as to enable the work to be performed with despatch and without any material ettort or annoyance.
